Hallam was 6 of 8 from the floor. Royce O'Neale chipped in eight points, six assists and five rebounds for the Pioneers (8-7, 4-1 Western Athletic), who closed the game on an 8-1 run.

Stephen Madison scored 19 points and Connor Hill had 12, including all three of his team's 3-pointers, for the Vandals (6-8, 2-2), playing their first WAC home game of the season.

Mike McChristian put Idaho ahead 48-47 on a layup with 1:35 to play, but Hallam's layup with 1:14 left gave Denver the lead back before Brett Olson, Cam Griffin and O'Neale each made two free throws to seal the victory.
